Build a Website

I've got a tiny website which was built with frontpage (5 simple pages). The bad is the webdesigner defined a fix content area which isn't dynamic related to the containing. If the content grows there isn't enough room. That's of course extreme bad practice. Another bad practise is, that all elements are positioned related to the bottom line. So if I would change the size of the content-area, everything is aligned wrong. What I need from you: There are only 5 pages. I want you to convert the existing content area from a fixed one to a dynamic one, which should automatically fit the avaiable content but have as minimum size the existing size. All content items should have the same position/layout, but should aligned in a better way than positioned relative to the bottom line (because if new content is in the main area, everything should stay at the defined place). I think it's quiet a simple task for a talented CSS hero. And 5 pages aren't a lot. Contact me if you want to see the current website.
